To a/ZZ who/it it 11mg/ concern:

- `Beit known that I, DANIEL I-Inrcns, ofCashlTown, in the county ot' Adams and State of Pennsylvania, have invented certain new and useful Improvements in Flows; and I do hereby declare the following to be a full, clear, and

exact description of the invention, suficient to enable others skilled in the art to which my invention appertains to make and use the saine, reference being had to the aceompanying drawil'igs, nl whicl 4- Figure l isfa side elevation, showing the landsidc andaeolter; Fig 0 a detail View, to

be hereinafter more fully referred to; Fig. 3, a side View,

representing the mold-board and share.

This invention comprises the following` features ot' improvement in plows: The moldboard is made in two parts, the lower one of 4which is rigidly attached and has the upper part hinged to it, so as to be adjusted to throw the furrow-slice uphill on elevated ground, or so as only to edge the ground up, a catch being. provided to hold thehinged portion in the proper position.

The invention also consists in the combinalionof certain parts forming the share side of a plow. The front part of the mold-board, or

an extension ofthe mold-board, but made separate from the parts already spoken of, is formed and attached in any suitable manner to the landside and plow-handle. The surface B, cast with the la-ndside, forms the front part ot' the mold-board, u. representing the dividing-line between the parts A Bf The upper portion, C, of the mold-board is hinged to the `part A at the line b, and has pivoted or hinged to itan arm, c, as shown in Fig. 1, provided with a series of notches which engage with a hook, (l, Ylixed `in the handle of the plow. A

p spring, e, presses on this notched arm, to hold itin engagement with the hook. By this means l the upper portion of the mold-board can be so adjusted as to throw the furrow-slice uphill on elevated ground, or so as vonly to f edge the ground up, by drawing in the hinged part toward the plow or throwing it out, as may be required. The cutter or colter D is made in about theform shown, and is adjustable, being held to the landside by a screw or screws, f,.passing through a slot or slots, g, so that the" extension of the colter or cutter beyond the mold-board in front can be lengthcned or shortened. The cutter is reversible, its two edges, h h', being similar, so that when onecdge has become dull or worn out the other can be presented forward until the eolter is entirely used up. The share E is attachml on the outer side of the mold-board i .f underneath. It is made in about 'tee i'orin shown, and is self-sharpening and reversible.

j is a triangular plate, 'Iitting a recess of the same formfot' which there are two, one in each face ol the share. The outer surface ot' this plate is flush with the face oi' the moldboard. The plate j prevents that part of the share underneath it from wearing.

F represents the plowpoint, which is made tapering, and softhat it can be used with either face uppermost. It is thus ren dercd seli`sl1a1] i ening. rlhe point is formed with a shank, (shown in' dotted lines, Fig. 1,) and 'is fastcned by a bolt, 7;, through the landside, instead ofthijongh the mold-board, as is the case with inost'otli'er plows. Thus the nut o'f the `bolt 7.a', being on the inner side, is protected from being knocked loose by stones. 'Ihe heel G of the landside is made separate from the la-ndside and bolted thereto, so thatwhcn the heel wears out a new one can be attached to the old landside. LThe landside I-I is cast with the part Z, which is made fast te the beam I ot' the plow. A recess is also formed in this casting for receiving the colter, and a part of the mold-board above described is also a portion ofthe saine-casting On the top ofthe beam, at its rear end, is iixed a casting, in., .having ou its upper surface a series et' ridges, as shown in Fig. 2.

a is a liat spring or casting, attached to the plow-handle, and having notches in its free end, which correspond with ridges in plate on.. The beam-casting has a concave surtace at its rear end, as shown in Fig. l., and the casting on. has a corresponding convexity.
